LORD HOWE ISLAND BOARD Business Paper

ITEM Electrical Network Safety Management System RECOMMENDATION It is recommended that the Board adopt the Electrical Network Safety Management System for implementation by the Administration. BACKGROUND Earlier in 2016, the Board was advised by the Independent Pricing and Regulatory Tribunal (IPART) that they had taken over the role of the safety and reliability regulator for NSW electricity networks. The Board is defined as an Electricity Network Operator and accordingly has responsibilities under the Electricity Supply Act 1995 and Electricity Supply (Safety and Network Management) Regulation 2014 in maintaining a safe and reliable electricity network on Lord Howe Island. More importantly, the Board seeks to provide a safe and reliable electricity supply for the benefit of the community. The Board engaged a consultant in 2016 to prepare an Electrical Network Safety Management System for the Island’s electricity generation and distribution system, which will meet the requirement of the legislation and IPART. CURRENT POSITION Through this System, the Board is committing to take all reasonable steps to ensure that the design, construction, commissioning, operation, maintenance and decommissioning of its electrical network (or any part of its network):

• Is as safe as possible and the risk from such activities is as low as reasonably practicable (ALARP) or presents a negligible risk

• Complies with relevant legislation • Is supported by all necessary policies, plans, procedures, work instructions • Complies with IPART electrical network safety management system reporting

requirements. When standards or requirements change, the Board will take steps to comply with the most recent edition to the extent that is reasonably practical. The document explains that our management structure is appropriate for the small size and limited complexity of our electrical network, and we will resource any temporary deficiencies, including to fill any periods where our staff may be on leave, by the use of contractors.

Through these documents, the Board has empowered those detailed in the electricity management structure above to act in accordance with the relevant responsibilities, accountabilities and authorities detailed in the ENSMS. The major cost implications of the system’s implementation are:

1. A requirement to have an annual audit completed of the System’s implementation, and a report to IPART on the outcomes.

2. Annual refresher training for the Senior Electrical Officer and Electrical Apprentice in Resuscitation and Rescue from Live Electrical Equipment.

3. Relief contractors for the Senior Electrical Officer will need to have the above current training and competencies in working on high voltage equipment.

Attachment 1 is the combination of the 11 separate documents and one drawing into the Board’s Electrical Network Safety Management System. The 11 documents are:

• Electricity Network Safety Management System Policy • LHIB ENSMS Customer Electrical Installation Safety Plan • LHIB ENSMS Planning, Design and Construction Plan • LHIB ENSMS Maintenance Plan • LHIB ENSMS Operations Plan • LHIB ENSMS Bushfire Management Plan • LHIB ENSMS Emergency Management Plan • LHIB ENSMS Decommissioning Plan • LHIB ENSMS Communication and Reporting Plan • LHIB ENSMS Monitoring, Measurement and Audit Plan • LHIB ENSMS Public Electrical Safety Awareness Plan

RECOMMENDATION It is recommended that the Board adopt the Electrical Network Safety Management System Policy and documents for implementation by the Administration.

ASSOCIATED

LEGISLATION

Electricity Supply Act 1995 (NSW) – Section 106 empowers

regulations such as:

Electricity Supply (Safety & Network Management) Regulation 2014 – requires network operators to ensure safety of their distribution system which includes having a safety management system in accordance with AS5777 and this policy.

ASSOCIATED POLICIES Bushfire Mitigation Hardship Policy

1. Background

As a network operator, as defined under the Electricity Supply Act 1995, the Lord Howe Island Board (LHIB)

is required under the Electricity Supply (Safety & Network Management) Regulation 2014 to have an

“Electricity Network Safety Management System” (ENSMS). AS/NZS5577 Electricity Network Safety

Management Systems provides guidance on establishing and maintaining an ENSMS that is consistent with

industry engineering, technical and safety documents. More importantly, the LHIB seeks to provide a safe

and reliable electricity supply for the benefit of the community.

2. The Island Group

The Lord Howe Island Group, located 700 kilometres north-east of Sydney, includes Lord Howe Island,

Admiralty Islands, Mutton Bird Islands and Ball's Pyramid as well as the associated marine areas. The Lord

Howe Island Group is part of the State of NSW. The island was first settled in 1834. Today, the main

industry on the island is tourism. In 1982, the Lord Howe Island Group was included on the World Heritage

List, and in 2007 was one of fifteen World Heritage places to be included in t he National Heritage List.

The main and only inhabited island, which is volcanic in origin, is 11 km long and between 2.0 km and 0.3

km wide. It has an area of 14.55 km2, of which only 398 hectares is in the lowland settled area. The

northern and southern mountainous ends of the Island and a central section, form part of the Permanent

Park Preserve (similar to a National Park).

Most of the island is virtually untouched forest with many of the plants and animals found nowhere else in

the world. Other natural attractions include the diversity of its landscapes, the variety of upper mantle and

oceanic basalts, the world's southernmost barrier coral reef, nesting seabirds, and its rich historical and

cultural heritage.

The Island’s population comprises approximately 360 permanent residents and a maximum 400 tourists at

any one time.

The LHIB is established under the Lord Howe Island Act 1953 and has responsibility for the care, control

and management of the Lord Howe Island Group. Under the Act, the LHIB has a b road range of


responsibilities and provides the majority of services and infrastructure on the Island. These include the

airport, the wharf, waste management services, roads, tourism infrastructure, public buildings, wastewater

oversight and the regulation, and generation and supply of electricity.

3. Management Structure and Responsibilities

The responsibility for electricity generation and reticulation on Lord Howe Island fits into the LHIB structure

as follows:

0

The LHIB believes that our management structure is appropriate for the small size and limited complexity

of our electrical network, and we will resource any temporary deficiencies, including to fill any periods

where our staff may be on leave, by the use of contractors or consultants.

The LHIB has empowered those detailed in the electricity management structure above to act in accordance

with the relevant responsibilities, accountabilities and authorities detailed in the ENSMS.

4. Our Electricity Network

The Lord Howe Island Board’s generates and distributes electricity via an underground electrical reticulation

system servicing approximately 280 customers on Lord Howe Island only.

The electricity generation system is housed in a centrally located powerhouse and consists of 3 x 300kW

Detroit Series 60 diesel generating units. In addition to this there is 1 x 450 kW Cummins C55 D5 diesel

generating unit that provides backup power in the event of major failure of the Series 60 generators.

The underground electrical reticulation system is designed for a HV distribution voltage of 11kV but is

currently utilized at a transmission voltage of 6.6 kV. There is approximately 13 kilometres of underground

HV cable. There are no aerial conductors on the island distribution system.

Two 500 kVA padmount substations supply the HV reticulation system from the powerhouse and one 500

kVA padmount substation supplies the HV reticulation system from the standby generating unit. The se three

500 kVA padmount substations utilize ABB Safelink SF6 ring main units for HV control. There are basically

two 6.6kV feeders from the substations with an intertie between the two via the ABB ring main units.

The existing HV network protection systems at the Power House and standby generator are 25 amp, 6.6 kV

transformer fuses.

Ten smaller padmounts substations ranging in size from 50 kVA to 150 kVA convert this HV distribution

voltage to a nominal 400/230 volt 3 phase supply which is then distributed locally to all customers via

underground mains. These substations utilize Hazemeyer Magnefix MD400 ring main units for HV control

and both “F” frame and Quicklag circuit breakers for LV control.

The existing LV network protection systems in use on the network are:

Eaton Series NRX 1000 amp Air Circuit Breakers with Digitrip 520 controllers located on the main

powerhouse switchboard;

Thermal/magnetic MCB’s and moulded case CB’s located in both padmount substations and LV

distribution pillars.

Existing powerhouse generator protection is provided by Woodward EGCP-2 engine control units. Distillate

fuel is stored in 1 x 34,000 litre and 2 x 17000 litre underground fuel tanks at the powerhouse and is

delivered fortnightly by a contracted Lord Howe Island Sea Freight shipping agent.

The existing standby generator protection is provided by Cummins PowerCommand 2.2 engine control units

with onboard diesel storage.

There is approximately 120 kW of private grid connected solar arrays on the system. These are controlled

by SMA inverters with standard voltage, frequency and anti-islanding protection.

Electrical hotwater booster load is controlled by a frequency injection control system which limits the

operational hours of the electrical booster systems to non- peak periods. This system is monitored on a 24

hour basis and adjusted to suit changing seasonal load profiles.

All electrical installations on the island must comply with local Lord Howe Island Electrical Service Rules

which regulate electrical installations and connections in order to ensure a rel iable, stable electrical supply

for all customers. All electrical installations must a lso comply with AS/NZS 3000 Wiring Rules. All new

electrical installations, additions or alterations to electrical services require the submission of appropriate

application forms to allow a thorough assessment to be undertaken for these works.

All customer installations are fitted with standardized electrical demand metering and customers are

charged on a quarterly basis for all electrical consumption.

The location of electrical network assets is recorded on paper and is being transferred to our Geographical

Information System and a schematic representation of the network is included in our drawing system and

as displayed and pinned in the Powerhouse.


Our electricity network is managed by our Senior Electrical Officer with assistance from his apprentice.

Contractors are used for relief or special projects as required.

5. Purpose of the Policy

The purpose of the policy is to enable the Board to comply with the Electricity Supply (Safety & Network

Management) Regulation 2014 and more importantly to ensure:

a) The safety of members of the public, and

b) The safety of persons working on the LHIB network, and

c) The protection of property, and

d) The management of safety risks arising from the protection of the environment, and

e) The management of safety risks arising from the loss of electricity supply.

ELECTRICITY NETWORK SAFETY MANAGEMENT SYSTEM

CUSTOMER ELECTRICAL INSTALLATION SAFETY PLAN

1. INTRODUCTION This Plan is part of the Lord Howe Island Board’s (LHIB) Electricity Network Safety Management System (ENSMS) and addresses the safety impacts of a customer’s installation on the LHIB’s electricity network.

The LHIB is committed to ensuring a safe and reliable electricity supply to all our customers by designing, operating and maintaining our electrical network to as high a standard as reasonably practicable. Our commitment also includes minimising/reducing the risk of harm to people within electrical installations.

The LHIB has developed this Plan to meet this commitment and to comply with the requirements of the Electricity Supply (Safety and Network Management) Regulation 2014 (NSW) and AS5577-2013: Electricity Network Safety Management Systems.

2. INSTALLATION COMPLIANCE REQUIREMENTS Electrical contractors and the LHIB are required to comply with but not limited to:

LHIB Service Rules AS/NZS3000 Wiring Rules AS/NZS3000 Normative Referenced Documents AS/NZS3012 Electrical Installation – Construction and Demolition Sites Work Health and Safety Act and Regulation (NSW)

The NSW Service and Installation Rules will be used for guidance where the LHIB Service Rules are silent, but the LHIB decision on any provisions will be final.

Compliance with the following is recommended, but not essential, for all electrical contractors and the LHIB:

AS/NZS3760 In Service Safety Inspection and Testing of Electrical Equipment AS/NZS4836 Safe Work on Low Voltage Electrical Installations National Code of Practice - Managing Electrical Risks in the Workplace

3. ELECTRICAL INSTALLATION WORK 4.1 Purchasing a Property Prospective leaseholders on Lord Howe Island are encouraged to engage the services of a licensed electrical contractor to undertake a full electrical safety check to ensure the electrical installation within the building is safe and free from defects before purchase.

4.2 Maintaining an Electrical Installation Electrical installation owners are required by law to maintain their installation so it remains safe. The LHIB encourages customers to organise regular safety checks of their electrical installations by engaging the services of a licensed electrical contractor.

4.3 DON’T Do-It-Yourself

Do-it-yourself (DIY) renovations and repairs have become more popular in recent times. However, DIY electrical work is not only dangerous but is also illegal in NSW. You must always use a licensed electrical contractor for any electrical repairs or installation work.

If you have any safety concerns, please contact the LHIB’s Senior Electrical Officer for


advice. 4.4 Process for New Installations or Additions and Alterations The process for the connection of new installations to the network or for additions and alterations to existing installations is as follows:

a) Immediately it is known that a new supply or an addition and/or alteration is required, the appropriate application form or forms should be obtained from the LHIB’s offices or website, filled in with all the required information, signed by the customer responsible for the payment of the accounts, and lodged with the LHIB.

The ‘New Installation Application for Supply’ and “Notification of Proposed Additions and/or Alterations to Existing Electrical Supply” forms must indicate the full extent of the proposed installations where such information is known by the applicant at the time of making the application.

No work should be undertaken on behalf of the customer until approval for the proposed installation has been given by the LHIB.

b) The leaseholder’s licensed electrical contractor can then carry out the approved new installation or additions and alterations in accordance with the LHIB Service Rules, any conditions of the approval and AS/NZS3000 Wiring Rules including requirements for testing.

c) The LHIB Senior Electrical Officer will drill, fit and wire the Supply Authority supplied equipment on the meter panel where this is required.

d) Permission may be granted by the LHIB’s Senior Electrical Officer to connect an addition to an existing final sub-circuit or the connection of an additional circuit pending a certificate of compliance and inspection. Check with the Senior Electrical Officer before connection to the supply.

e) Within 14 days of completion, the electrical contractor must submit a “Certificate of Compliance” to the Senior Electrical Officer.

f) The Senior Electrical Officer will inspect all commercial and industrial electrical works and all major works for domestic installations for all submitted “Certificates of Compliance”.

Minor electrical works for domestic installations will be inspected randomly and based on electrical contractor performance.

4.5 Unsafe or Defective Installations The LHIB may disconnect premises from (or refuse to connect premises to) its distribution system if the Senior Electrical Officer reasonably considers that the electrical installation on the premises is (or is likely to become) unsafe in accordance with Section 39 of the Electricity Supply (Safety and Network Management) Regulation 2014. Section 40 of the same Regulation allows for immediate disconnection if it is reasonably considered that there is an immediate danger to life or property or an immediate risk of starting a fire if the premises continue to be connected to the distribution system.

4.6 Disciplinary Action for Electrical Contractors LHIB may take disciplinary action against electrical contractors where it is known that they have:

Undertaken defective or unsafe electrical work including non-conformance with AS/NZS3000;

Failed to rectify breaches when notified;


Failed to notify the LHIB of notifiable electrical installation work; Connected installations or electrical work without approval; Failed to test and therefore failed to comply with AS/NZS3000; Performed electrical work whilst unlicensed or using unlicensed/unqualified

persons; Interfered with metering equipment.

Disciplinary actions are likely, depending on the seriousness of the breach, to include:

Verbal or written notice; Formal interview or counselling session; Notification to NSW Fair Trading; Reassessment of the frequency and extent of electrical audits; Other actions as considered appropriate at the time.

The electrical contractor has the right of reply before any disciplinary action is taken.

4. REPORTING LHIB will meet its reporting obligations to NSW Fair Trading for incidents involving electrical articles or electrical installations in accordance with the LHIB ENSMS Communication and Reporting Plan.

5. PLAN REVIEW

MAINTENANCE PLAN 1. INTRODUCTION This Plan is part of the Lord Howe Island Board’s (LHIB) Electricity Network Safety Management System (ENSMS) and addresses the maintenance aspects of the LHIB’s electricity network.

LHIB is committed to ensuring a safe and reliable electricity supply to all our customers by maintaining our network.


2. MAINTENANCE PLAN The LHIB electrical network must be maintained to ensure the electrical equipment is always in sound operating condition to perform the functions for which it was designed. This Plan lays out the maintenance requirements for the electrical network equipment.

2.1 Maintenance Standards The LHIB will follow industry practice and use the guidance of manufacturer’s instructions and the following documents for the maintenance of electrical network equipment on the island:

AS2467 Maintenance of electrical switchgear AS2676 Guide to the installation, maintenance, testing and replacement of

secondary cells in buildings AS60422 Mineral insulating oils in electrical equipment - Supervision and

maintenance guidance AS61000.3.100 Electromagnetic compatibility (EMC) - Limits - Steady state

voltage limits in public electricity systems Ausgrid Electrical Safety Rules EC12 Guide to working on underground cables EC19 Guide to the inspection of Customers’ electrical installations ENA DOC 022 ENA Industry Guideline for SF6 Management. ENA DOC 025 EG-0 Power system earthing guide - Part 1: management

principles ENA EG1: Substations, earthing guide ISSC3 Guide to tree planting and maintaining safety clearances near power lines ISSC24 Guide to Electricity Workers’ Escape and Rescue Procedures LHIB Operational Plan Safework Australia General Guide, Information Sheet and Code of Practice for

Working in the Vicinity of Overhead and Underground Electric Lines Safework Australia Code of Practice - Excavation work

2.2 Non-Compliance with Standards Should the LHIB need to perform maintenance that is a deviation from standards, codes, guidelines and/or statutory requirements, we will justify the deviation to achieve at least an equivalent safety outcome through the following (as applicable):

A formal safety assessment Literature review Consultant report, and/or Incident investigation outcomes.


3. SPECIFIC MAINTENANCE REQUIREMENTS Maintenance tasks for specific items of plant and equipment shall be carried out as follows:

3.1 Powerhouse and Standby Generator

The Powerhouse and standby generator equipment will be maintained in accordance with manufacturer requirements and at least every 300 hours. “A”, “B” and “C” Maintenance

Tasks sheets shall be used to ensure all maintenance tasks are completed and recorded.

The standby generator is to be:

Visually inspected monthly and run off-load for approximately 60 minutes. Visually inspected and run every 3 months for approximately 6-7 hours at a

minimum 50% of full island load. Protection relays to be tested every 5 years by current injection and timing trip

tests.

3.2 Substations Substations are to be maintained as follows:

Visually inspected for defects and assessed for obvious signs of deterioration and/or malfunction every year.

Transformers maintained as follows: o Free of rust and oil leaks. o Transformer oil to be sampled and tested every 5 years – water content,

dissolved gas analysis, dielectric breakdown voltage. o Bushings and fuses cleaned yearly. o Thermography on the High Voltage (HV) and Low Voltage (LV) ends

yearly. Earths tested every 10 years initially and every 5 years once equipment is 20

years old. Earthing managed as required by ENA DOC 025 EG-0 Power system earthing

guide - Part 1: management principles.

3.3 High Voltage Switchgear 3.3.1 Hazemeyer Switchgear

Hazemeyer high voltage switchgear is to:

Be visually inspected for defects every year. Be cleaned annually using the manufacturer’s procedure.

A program for replacement of the Hazemeyer switchgear is to be established so that all units are replaced by 2025 due to a record of industry failure. It is known that the failure of these units has typically been due to a lack of maintenance. A continued commitment to annual maintenance is mandatory.

3.3.2 SF6 Switchgear

SF6 switchgear to be:

Inspected annually to determine any further actions. Cleaned every 5 years. Insulation and contact resistance tested every 5 years. Partial discharge and corona tested every 5 years if possible. Operated to ensure functionality. Managed as required by the manufacturer and ENA DOC 022 ENA Industry

Guideline for SF6 Management. Disposed of in accordance with environmental requirements at end of life.


3.4 Low Voltage Distribution Network The following items of the Low Voltage network are to be inspected 6 monthly:

Pillars Street lights and bollards Numbers, labels and warning/danger signs

Distribution substation Maximum Demand Indicators (MDIs) are to be read monthly and readings assessed to determine the status of the load on each transformer.

4. DEFECT RECTIFICATION Any defects found by the inspection and maintenance regime shall be rectified according to priorities as assessed by the Senior Electrical Officer. Defects that do not pose a threat to safety or system reliability, what could be called “discretionary maintenance”, may be rectified as workloads permit.

5. REPAIRS Supply should be restored to as much of the network as possible and repairs implemented as soon as possible using suitably qualified, competent and authorised persons. Isolation for repairs to the network shall be carried out in accordance with the LHIB Electrical Network Operations Plan.

Contractors may be required to implement repairs which are beyond the scope of island electrical staff.

6. NETWORK SPARES Adequate spares shall be carried to allow immediate repair of the network should an unplanned outage occur as a result of equipment failure. The following is considered a minimum list of spares:

1 x Hazemeyer switchgear – circuits: in and out and transformer 50m x HV cable – 16mm² XLPE Copper 2 x inline cable joints for HV cable 1 x Termination kit and leads for Hazemeyer switchgear A full set of each relevant HV fuse size One distribution transformer 2 x LV circuit breakers for generator output Miscellaneous spares such as MDIs, F Frame circuit breakers, CT’s and Quicklag

circuit breakers.

No spare generator output transformers are needed as the island could cope with just one if necessary. If a failure occurred, the minimum 20 week lead time on a transformer to suit the Island’s network would necessitate the immediate ordering of a replacement transformer.

7. RECORDS All records of inspection and maintenance activities are to be stored by the Senior Electrical Officer for future reference, defect trend analysis, auditing and/or reporting.

ELECTRICITY NETWORK SAFETY MANAGEMENT SYSTEM OPERATIONS PLAN

1. INTRODUCTION This Plan is part of the Lord Howe Island Board’s (LHIB) Electricity Network Safety Management System (ENSMS) and addresses the operation of the LHIB’s electricity network. LHIB is committed to ensuring a safe and reliable electricity supply to all our customers when we need to operate our electrical network. The LHIB has developed this Plan to meet this commitment and to comply with the requirements of the Electricity Supply (Safety and Network Management) Regulation 2014 (NSW) and AS5577-2013: Electricity Network Safety Management Systems.

2. OPERATIONS The operation of network equipment shall be carried out safely by suitably qualified, competent and authorised personnel using suitable PPE and the guidance of Ausgrid’s Electrical Safety Rules. Operational activities shall include isolating, testing de-energised, earthing and issuing/cancelling access permits. Staff and contractors shall be inducted prior to any operational work and authorised in accordance with Section 4. An operator shall seek guidance if operations fall outside normal operating parameters or if it lies outside their skillset. A suitably qualified consultant may also be contacted if the situation lies outside the skills and knowledge of the island electrical management team or the team is not contactable.

3. NETWORK SCHEMATICS & MAPPING A High Voltage Operating Diagram is to be displayed at all times at the Powerhouse Operations Room and pinned to show the present state of the network. Geographical mapping of electrical network assets is available within the LHIB Geographical Information System (GIS). This information is available to those with access to the LHIB network at the Bowker Avenue offices.

4. AUTHORISATION LHIB shall ensure that ALL staff and contractors involved with the High Voltage (HV) network are qualified and authorised for the work to be performed using Appendix A and recorded in an Excel spreadsheet titled “LHIB HV Authorisation Register”. This register shall be held and managed by the Senior Electrical Officer. The authorising officer must be satisfied that the person is qualified and competent to perform the required functions before issuing an authorisation card or when renewing authorisations. This authorisation allows staff to perform the identified functions on Lord Howe Island only for the period identified on their authorization card. Authorisations from other companies do not allow electrical workers to work or operate at Lord Howe Island. Authorisation of staff and contractors will include the following:

(a) Open HV cabinets (b) Supervise HV maintenance or installation works (c) Operate HV switchgear (d) Lock out/Tag out HV equipment (e) Test HV equipment de-energised (f) Earth/Short Circuit HV equipment (g) Issue and Receive Access Permits (h) Induct workers for work on or near HV equipment (i) Write switching sheets.


An authorisation card may be issued or renewed at the discretion of the authorising officer, dependent upon demonstration and/or maintenance of competence.

The “LHIB HV Authorisation Register” will include:

(a) Authorisation number; (b) Name of authorised person; (c) Company; (d) Authorisation type; (e) Date of issue; (f) Date of authorisation expiry. (g) File reference for qualifications and/or evidence of competence.

Records used to issue an authorsiation such as copies of qualifications or evidence of competence are to be stored for future reference.

LHIB may withdraw an authorisation at any time and the Authorisation Card is to be returned to the LHIB.

Authorisation in the future may be via the Australian Electricity Supply Industry (ESI) Skills Passport as may recording of all ESI training. Details of this system can be found at www.esipassport.com.au

5. COMPETENCY, QUALIFICATIONS & TRAINING

As stated above “The authorising officer must be satisfied that the person is qualified and competent to perform the required functions before issuing an authorisation card or when renewing authorisations.”

Competency/qualification requirements shall include:

Electrician (Supervisor) License Certificate III in Electrotechology Electrician, Electrical Supply Industry -

Distribution or similar General Construction Induction Card Experience in the operation of networks and HV equipment; Knowledge and experience using the high voltage equipment utilised on Lord

Howe Island; Suitable qualifications and/or units of competence such as those detailed below:

http://www.esipassport.com.au/


6. AUTHORISED WORKER RESPONSIBILITIES

Authorised workers shall:

(a) Have authorisation cards readily available when working on the island; (b) Produce their card when requested; (c) Secure the card to reduce the likelihood of unauthorised use; (d) Report lost or stolen cards to LHIB as soon as practical; (e) Ensure all training and competencies are current and copies of certificates

provided to LHIB; and (f) Ensure that they only undertake work for which they are competent and authorised

to perform.

7. SENIOR ELECTRICAL OFFICER UNAVAILABLE

The Senior Electrical Officer may be unavailable for reasons such as illness, injury, or on leave. In this absence, an authorised contractor shall be used to carry out any authorised operational activities.

If an authorised contractor is not on site and a safety issue or emergency arises, an authorised contractor may direct LHIB staff to perform certain functions before an authorised contractor arrives on site.

8. PROTECTION COORDINATION

The high voltage protection for the island high voltage electrical network has been in place for some time. A review by Jacobs Group (Australia) Pty Limited in 2015 details the protection methodology and coordination details and forms part of this Operations Plan.

9. OPERATION OF HAZEMEYER SWITCHGEAR

The Hazemeyer switchgear is not to be operated on load and arc-flash clothing and face shields are to be used when operating at no-load.

10. SWITCHING SHEETS

Due to the simplicity of the network and the knowledge of the Senior Electrical Officer, it is deemed that switching sheets will generally not be required. However, if an operator is required to operate the network and is unfamiliar with the network, a switching sheet should be developed by a suitably qualified and authorised person (which could be the operator) prior to the work commencing.

11. ISOLATION, EARTHING AND ACCESS PERMITS

Isolation and lock out/tag out of the isolated equipment shall be in accordance with the Ausgrid Electrical Safety Rules as will earthing/shorting of the isolated equipment. Appropriate earthing/shorting equipment shall be used and installed and/or removed by authorised operators only.

The LHIB Access Permit shall be utilised to access isolated HV equipment using the guidance of Ausgrid’s Electrical Safety Rules. Yellow or white tape barriers may be needed to define the isolated equipment and work area using the guidance of Ausgrid’s Electrical Safety Rules.


12. ABNORMAL OPERATIONS

The Senior Electrical Officer shall use knowledge, skills and training to manage any abnormal situations including emergencies (also refer LHIB ENSMS Emergency Management Plan). Safety will always be a priority in any actions taken.

In an unplanned outage situation, the electricity supply can be restored very quickly due to the small size of the island. It is however a requirement that a patrol of assets be carried out before restoring supply for public safety reasons e.g. a car accident involving network assets.

Items of plant that have failed or need repair are to be isolated and repaired using the guidance of the Ausgrid Electrical Safety Rules and supply should be restored to as much of the network as possible. Repairs are to be implemented using only authorised persons, along with relevant testing and recommissioning works.

Priority will be given to the hospital and any “life support” customers when restoring supply after an unplanned outage.

No further risk management planning is considered necessary for abnormal situations due to the small size and limited complexity of the network.

The LHIB Business Continuity Plan will include requirements for abnormal operations once updated.

13. BLOWN HV FUSE

All three fuses must be replaced when one fuse has blown on any transformer on the island.

14. LOAD SHEDDING

It is not anticipated that load shedding should be necessary at any stage due to the sizing of the generators and the remote location of the backup generator which is capable of supplying all the electrical load to the island.

However, if load shedding was required, then all but the hospital load would be cycled on a three hourly basis. Any “life support” customers would also be excluded from the load shedding program unless other arrangements have been made.

15. BLACK START

Restoring the electricity supply after a complete outage to the island is easily achieved following standard restart procedures. Electrical supply restorations to the hospital is considered a priority under these circumstances.

16. LOSS OF VOLTAGE REGULATION

Loss of voltage regulation at the Powerhouse would necessitate swapping to the Standby Generator or manual control of voltage until repairs are implemented. The decision by the Senior Electrical Officer will depend on circumstances at the time.

17. COMMUNICATION OUTAGE

The loss of the LHIB radio network or phone service is not considered a serious issue for the management of the network due to the limited size of the island and network, and the number of network staff. The Senior Electrical Officer or authorised contractor are required to follow all parts of this plan and so the risk from a communication outage is minimal.


18. DIESEL STORAGE

Adequate quantities of diesel are to be stored at the Powerhouse and Backup Generator. Diesel will be cleaned on a six monthly basis to ensure trouble-free operation of the generator engines.

19. HV TOOLS

HV tools such a HV operating stick, earthing/shorting kits and tester are to be available. These are to be maintained in a suitable condition and the stick tested every 2 years.

20. NOTIFICATION OF PLANNED OUTAGES

Notification for planned outages will be in accordance with the LHIB Electrical Network Communications and Reporting Plan.

21. INCIDENT MANAGEMENT

The Senior Electrical Officer will take charge of electrical incidents to ensure electrical safety on behalf of the LHIB. The Senior Electrical Officer will work in with other emergency services during an incident.

All electrical incidents are to be investigated (refer LHIB Document 5 - Safety Incident Management, Reporting and Investigation), recorded and reported (refer LHIB ENSMS Communication and Reporting Plan) including unplanned outages.

Incidents investigations are to be overseen by the Manager of Infrastructure and Engineering Services and generally undertaken by the Senior Electrical Officer unless an assessment determines that an independent lead investigator is necessary. The independent lead investigator may be a manager from another department or an external consultant.

22. RECORDS

Records of planned and unplanned outages and incidents are to be retained by the Senior Electrical Officer in the Network Incident Register.

23. STANDARDS

The following documents provide guidance for the operation of the island network:

ENA Doc 024 National guideline for management of tools and equipment used in the electricity supply industry

ENA NENS03: National guidelines for safe access to electrical and mechanical apparatus

ENA NENS04: National guidelines for safe approach distances to electrical and mechanical apparatus

ELECTRICITY NETWORK SAFETY MANAGEMENT SYSTEM BUSHFIRE MANAGEMENT PLAN

1. INTRODUCTION

This Plan is part of the Lord Howe Island Board’s (LHIB) Electricity Network Safety Management System (ENSMS) and addresses the management of bushfire risks relating to the LHIB’s electricity network.

LHIB is committed to preventing bushfires initiated by the electrical network by designing, maintaining and operating our electrical network to as high as standard as reasonably practicable and in accordance with industry standards.


2. BUSHFIRE STATUS The bushfire risk on Lord How Island is assessed as low due to the island being sub-tropical in nature and the lush vegetation that prevails.

3. PREVENTATIVE ELECTRICAL STRATEGIES The whole electrical network on Lord Howe Island is installed underground and all future network extensions are to be installed underground. The high voltage network is also protected at the powerhouse and standby generator by high voltage fuses. The LHIB will comply with our design, construction, commissioning, maintenance, operations and decommissioning plans to assist with bushfire prevention.

The propensity to start a bushfire in such circumstances is extremely low.

4. HARDSHIP POLICY

The LHIB electrical network is underground, there are no private overhead power lines or high voltage customers and there is a low risk of a bushfire on the Island. For these reasons, electrical customers will not be in financial hardship as a result of a need to upgrade, repair or maintain their private overhead assets.

The LHIB has in place a Bushfire Mitigation Hardship Policy, to comply with the requirements of the Electricity Supply (Safety and Network Management) Regulation 2014 (NSW) and AS5577-2013: Electricity Network Safety Management Systems.

5. PRIORITIES Priorities for the electrical network in an emergency condition including restoration of the electricity supply are in the following order:

1. Safety of LHIB electrical network staff and the community. 2. Electricity supply to the hospital, airport and Emergency Operations Centre. 3. Electricity supply to any “life support” customers. 4. Electricity supply to the telecommunications network. 5. Electricity supply to evacuation centres. 6. Electricity supply to the business community. 7. Electricity supply to residential areas.

6. RESOURCES Existing staff resources are considered adequate for emergency conditions. However, contractors may be required to assist with repairs after an event, as detailed in the LHIB ENSMS Maintenance Plan.

Equipment spares are also detailed in the LHIB ENSMS Maintenance Plan.

7. ELECTRICAL STAFF SAFETY A swift response in emergency situations is critical, but safety shouldn’t be compromised. It is therefore necessary for electrical staff when attending to an emergency and on their arrival at the site to:

• Visually check for hazards, assess the risk and establish risk controls to be implemented.

• Coordinate work activities with other emergency services. • Continue with normal work procedures and manage hazards and risk.

Relief network operators shall seek guidance from the Senior Electrical Officer or the Manager of Infrastructure and Engineering Services if operations fall outside normal operating parameters or their skillset.

8. NETWORK RESPONSE TO EVENTS The LHIB may need to respond to various natural and man-made events and isolate the electricity supply. Any advice to the community will be in accordance with the LHIB ENSMS Communication and Reporting Plan.

The following provides planning for specific foreseeable events:

8.1 High Seas

High seas would not normally pose a threat to the electricity supply on the island. However, sea levels and their effects will be monitored to ensure safety and isolation of the supply to affected electrical assets would occur if necessary.

8.2 Storm Water

Excessive rain may cause storm water to inundate low lying areas of the township, particularly around the school area. This may necessitate isolation of the electricity supply to parts of the network in that area to ensure safety and prevent electrical damage to the electrical assets.

The Senior Electrical Officer shall monitor Bureau of Meteorology predictions and will determine in conjunction with the LHIB Manager Infrastructure and Engineering Services / Chief Executive Officer if the electricity supply shall be isolated.

Once water levels have receded and are considered unlikely to inundate electricity assets again, the assets shall be inspected and cleaned if required, dried and tested as necessary before the supply is restored.


8.3 Tsunamis A land inundation type tsunami has the potential to damage electrical assets, particularly if the electricity supply has not been isolated beforehand. The Senior Electrical Officer in conjunction with the LHIB Manager Infrastructure and Engineering Services / Chief Executive Officer, will decide if the electricity supply to areas that may be affected should be isolated prior to any predicted tsunamis. The Senior Electrical officer may have to make the decision to isolate if senior LHIB staff are unavailable and time is short.

The electricity supply to Evacuation Centres for tsunamis at the Golf Club and corner of Anderson Road and Middle Beach Road is to be maintained whenever possible and if safe to do so.

Once the tsunami threat has abated, the assets shall be inspected and cleaned, dried and tested if necessary by the LHIB electrical staff before the supply is restored.

8.4 Vandalism Vandalism of network assets on the island generally takes the form of graffiti on substations and minor damage to street lighting and poses little threat to electricity supply security.

The response to more serious vandalism will depend on the extent of damage. The community are encouraged to report any suspicious behaviour to the police to prevent or limit vandalism.

8.5 Terrorism Threat of terrorism is very low on the island given that the primary means of access to the island is via air and the associated security screening. Members of the public are encouraged to report any suspicious activity to the local police.

The network response to any terrorism act will depend on the assets damaged or destroyed. The backup generator at its remote location from the powerhouse helps provide security of supply if the powerhouse was destroyed or damaged by a terrorist attack.

Spare equipment for network repairs and repair strategy following a terrorist attack, or from any source of damage, is detailed in the LHIB ENSMS Maintenance Plan.

8.6 Fire Bushfires are unlikely due to the nature of the island (refer LHIB ENSMS Bushfire Management Plan).

The LHIB has emergency and evacuation plans for fires at their office, depot and powerhouse to help ensure the safety of personnel. Plans are displayed prominently on notice boards throughout the office and buildings.

Any electrical assets that catch fire will be electrically isolated as soon as practicable before the Rural Fire Service, if required, controls the fire.

8.7 General Network Faults Miscellaneous network faults will occur from time-to-time. The Senior Electrical Officer will isolate the affected part of the network, restore supply to as much of the network as possible and then organise repairs (in accordance with the LHIB ENSMS Operations Plan).

DECOMMISSIONING PLAN 1. INTRODUCTION This Plan is part of the Lord Howe Island Board’s (LHIB) Electricity Network Safety Management System (ENSMS) and addresses the safety and environmental impacts of decommissioning of any component of the LHIB’s electricity network.

2. GENERAL REQUIREMENTS All decommissioning works are to be performed in accordance with Australian Standards, codes, guidelines, and statutory requirements. Any deviation from such requirements are to be assessed and justified as to achieve at least an equivalent safety outcome through the following (as applicable):

Formal safety assessments; Literature review; Consultant report; and\or Incident investigation outcomes.

All staff, consultants or contractors involved in decommissioning of the electrical network, or part thereof, shall be suitably trained, qualified and competent. The Senior Electrical Officer must be satisfied that all personnel involved in decommissioning works are suitably trained, qualified, competent and equipped to perform the work.

3. SAFETY Any component of the network that is to be de-energised must be isolated, locked and tagged, tested de-energised and earthed/short circuited. An access permit must be issued before any network component can be removed. Ausgrid’s Electrical Safety Rules shall be followed for this process to ensure safety. The integrity of any remaining network assets is not to be compromised.

Any isolated cables left in the ground that may have unwanted voltages induced or transferred into them are to be suitably terminated and/or insulated at any exposed parts.

No asbestos or PCBs are expected to be found as part of the electrical network as no equipment has been identified containing either.

4. ENVIRONMENTAL As much of the removed network components shall be recycled as possible when any decommissioning of the network or parts thereof occurs. Recycling particularly applies to transformer oil and SF6 and these shall be suitably contained and then recycled. Spill kits are likely to be required in case of accidental transformer oil escape when transformer works are in progress.

Disposal of goods will be in accordance with environmental laws and guidelines including the Protection of the Environment Operations Act 1997 and requirements of the NSW Environmental Protection Authority.

stakeholders. Identify statutory reporting requirements. Comply with the requirements of the Electricity Supply (Safety and Network

Management) Regulation 2014 (NSW) and AS5577-2013: Electricity Network Safety Management Systems.

2. COMMUNITY Electricity customers are to be notified of planned outages at least 4 business days before the date of the interruption. Extended unplanned outages will also require some community notification. We will consult with the community as appropriate when changes to electricity generation or the distribution network are likely to have an effect on the community or environment. The level of consultation will be determined by the issue at the time and the likely significance to the community. The dissemination of information and consultation for the above scenarios may include:

Mail outs (householders) through the local Post office Community meetings Quarterly LHIB meetings Radio Local newspaper LHIB Website Social media Development application process.

The community are encouraged to contact the Senior Electrical Officer if there are any concerns about electrical safety or excavation works in case of underground electrical mains. There is no formal Dial Before You Dig service like that found on the mainland. The same service on the Island is initiated through contact with the Senior Electrical Officer and does not incur costs to any customers.

3. LOCAL EMERGENCY SERVICES The Local Emergency Management Committee comprises representatives from all local emergency and support agencies i.e. State Emergency Service and Rural Fire Service (additional information is provided on the LHIB website - http://www.lhib.nsw.gov.au/services/emergency-services). The committee is supported by the LHIB through the provision of administrative services. It is responsible for the planning, preparation, response and recovery of all matters relating to emergencies that may affect the local community.

This close relationship ensures that consultation and management of issues associated with the electrical network does occur.

ELECTRICITY NETWORK SAFETY MANAGEMENT SYSTEM MONITORING, MEASUREMENT AND AUDIT PLAN

1. INTRODUCTION This Plan is part of the Lord Howe Island Board’s (LHIB) Electricity Network Safety Management System (ENSMS) and addresses the monitoring, measurement and auditing for the LHIB’s electricity network.

The LHIB is committed to ensuring a safe and reliable electricity supply to all our customers through the monitoring, measuring and auditing of the electrical network performance.


2. MONITORING AND MEASURING All elements of the LHIB ENSMS shall be internally checked at the end of each IPART reporting period to ensure all requirements have been achieved. Failure to meet requirements will require an action plan to be developed to ensure compliance and/or a review of requirements to ensure they are realistic and in accordance with industry standards and practice at the time.

2.1 Planning, Design, Construction, Commissioning, Decommissioning

The annual review by the Senior Electrical Officer prior to the external IPART audit shall check that all requirements for planning, design, construction, commissioning and decommissioning has been performed in accordance with the relevant LHIB Plans, Australian Standards, codes and guidelines for these items.

The Senior Electrical Officer shall also monitor and audit contractor projects relevant to the network, to ensure compliance with requirements.

2.2 Maintenance

Maintenance works as described in the LHIB ENSMS Maintenance Plan shall be audited to ensure scheduled targets have been achieved. Failure to meet targets will require an action plan to ensure compliance and/or a review of targets to ensure that the targets are realistic and in accordance with industry standards and practice at the time.

2.3 Reliability

The number and length of unplanned outages will be monitored to ensure the number and frequency of interruptions to the electricity supply does not deteriorate over time without relevant cause.

2.4 Power Quality

The voltage output at the Powerhouse is monitored and alarms will highlight if there is an excessive deviation in Powerhouse output voltage.

The Senior Electrical Officer will respond to power quality complaints from customers and may use spot checks or loggers to check power quality.


3. AUDITING

The LHIB ENSMS will be audited for/by IPART annually in accordance with IPART’s

‘Electricity Networks Audit Guideline’. The Senior Electrical Officer will conduct a review to ensure that the ENSMS is in order prior to the audit.

Due to size of the network and associated operations, we believe that an external audit should not normally be necessary and the annual review by the Senior Electrical Officer and the audit for IPART will be adequate. We will however, carry out internal or independent auditing of our ENSMS on an as needs basis.

Auditing of electrical staff and LHIB electrical network contractors will be carried out on an informal basis.

4. ENSMS REVIEW

The ENSMS is to be amended as required to meet legislative, organisational structure changes, operational experience or events, coronial findings and Royal Commission recommendations. Changes to the ENSMS will require approval from the Manager of Infrastructure and Engineering Services.

A review and update to the ENSMS shall be carried out at least every 5 years.

5. ADDRESSING AUDIT OR REVIEW FINDINGS

Changes identified to the LHIB ENSMS as part of an audit or review shall be made as soon as reasonably practical.

PUBLIC ELECTRICAL SAFETY AWARENESS PLAN 1. INTRODUCTION This Plan is part of the Lord Howe Island Board’s (LHIB) Electricity Network Safety Management System (ENSMS) addresses the methods of informing the public of electrical safety issues related to the LHIB’s electricity network and electrical safety issues with customer’s electrical installations.

The LHIB is committed to ensuring a safe and reliable electricity supply to all our customers by operating and maintaining our electrical network to as high as standard as reasonably practicable.

The LHIH has developed this Plan to meet this commitment and to comply with the requirements of Electricity Supply (Safety and Network Management) Regulation 2014 (NSW) and AS5577-2013: Electricity Network Safety Management Systems.

Our initiatives (see Section 3) are identified from incidents and accidents, our network risk analysis and other data sources.

The LHIB will inform the Island community of the identified risks and recommended controls using all reasonable means. These means are likely to include specific newsletters, board newsletters, local radio, community noticeboards, school visits and the web (refer LHIB ENSMS Communication and Reporting Plan).

2. OBJECTIVES The LHIB’s ENSMS Public Electrical Safety Awareness Plan objectives are to:

Reduce the risk of harm to the community from electrical issues; Raise awareness of the hazards related to the Island’s electricity network; Raise awareness of electrical issues identified through our electrical safety

initiatives; Encourage the safe electrical practices.

3. ELECTRICAL SAFETY INITIATIVES 3.1 Underground Cable Safety

The LHIB has an underground cable network for the distribution of electricity on the Island. You should check with us before carrying out any excavation works to ensure safety at the site and eliminate electrical network damage. This applies to works on both private and public lands.

The LHIB’s Senior Electrical Officer will provide advice and/or conduct a cable location as required - this is a free service.

Any suspected damage to the electricity network should be immediately reported to the LHIB's Senior Electrical Officer.

The Safework Australia’s General Guide for Working in the Vicinity of Overhead and

Underground Electric Lines and Working in the Vicinity of Overhead and Underground

Electric Lines Information Sheet provides useful guidance for work near underground powerlines.

3.2 Damaged Network Equipment

LHIB encourages members of the public to report any damage to network equipment such as transformers, pillar boxes, underground cables or streetlights.


3.3 Switchboard Upgrades Residual current devices, or safety switches as they are often called, are now used to protect electrical circuits when constructing or modifying a new building. These safety switches help to significantly improve customer safety on outgoing installation circuits. Safety switches are easily identified by a “test button” located on the front of the switch. The LHIB strongly recommends that you replace all old circuit protection with safety switches. You will need to contact your electrical contractor to arrange for the replacement works.

3.4 Electric Shocks Electric shocks, no matter how small, from appliances, switchboard boxes, water taps, metallic downpipes and roofs, require investigation from suitably qualified personnel. Contact the LHIB’s Senior Electrical Officer as soon as possible for assistance if this occurs. In the meantime, ensure you and your family stay clear of all metallic items.

3.5 Electrical Product Safety Recalls Electrical products are recalled from time-to-time due to safety concerns. We recommend that the community regularly check the ACCC’s Product Safety Recall Australia’s website, www.recalls.gov.au and/or sign up for their email alerts. The LHIB will seek to notify the Island community where we are aware of electrical products that we believe are likely to affect the wider community.

3.6 DIY Electricity Safety Do-it-yourself (DIY) renovations and repairs have become more popular in recent times. However, DIY electrical work is not only dangerous but is also illegal in NSW. You must always use a licensed electrical contractor for any electrical repairs or installation work. If you have any safety concerns, please contact our Senior Electrical Officer for advice.

3.7 Lightning Awareness Lightning can have disastrous and devastating consequences. The Island community should take precautions when storms are likely. Precautions for lightning include:

Install lightning protection in switchboards and/or use surge protection boards on sensitive electronic equipment;

Shut down computers and unplug appliances before any storm activity. Seek shelter indoors and avoid contact with electrical appliances, metal pipes and

metal fixtures, stay clear of windows and glass doors and avoid using fixed telephones.

3.8 General Electrical Safety The following advice should be used as a guideline for electrical installations:

• Install safety switches on all circuits (see Section 3.3) • Test safety switches with the “test button” every 6 months if possible; • Never put a metal object in a toaster or power point. • Don’t use electrical appliances or power cords where there is water; • Use an appropriately rated extension lead and one that is not too long; • Unwind extension leads before use to help prevent overheating; • Never use more than one double adaptor in a single power point and try to

avoid their use altogether; • Don’t overload power boards; • Use a licensed electrical contractor if renovating; • Contact us before digging (see Section 3.1); • Replace damage appliances or leads;

http://www.recalls.gov.au/


• Check for wires before drilling into walls, floors and ceilings; • Keep a battery-operated torch in case of a blackout.

3.9 Electrical Safety of Emergency Safety Personnel

ENA DOC 008 provides guidance on electrical safety of emergency safety personnel. The LHIB encourages emergency service personnel to become familiar with the requirements of this document.
